- ▸ Hardener for high-solids, low-VOC two-component (2K) polyurethane coatings
- ▸ Crosslinks hydroxyl acrylic and polyester resins into weatherable, light-stable films with reduced solvent demand
- ▸ High-solids automotive refinish and OEM coatings
- ▸ Low-VOC industrial-maintenance and protective coatings
A grade-specific Safety Data Sheet (SDS) — with the complete hazard classification, handling precautions, and transport information — is supplied with every shipment and available on request. Confirm all safety and regulatory details against the SDS for your specific grade.
Request SDS →The low-viscosity grade lets formulators reach high-solids, lower-VOC two-component (2K) polyurethane formulations with less solvent while retaining the weatherability and light stability of the HDI isocyanurate backbone. Crosslinked with hydroxyl-functional acrylic or polyester resins, it produces durable, UV-stable films suited to high-solids automotive refinish and OEM coatings, industrial-maintenance systems and protective topcoats subject to tightening VOC limits. RawSource supplies low-viscosity HDI trimer polyisocyanate in bulk to coating and CASE formulators
Comparable to Desmodur N3600: RawSource supplies this as an independent equivalent (an offset) to Desmodur N3600 — it is a low-viscosity HDI isocyanurate trimer polyisocyanate. It is not genuine Desmodur N3600-branded material, and RawSource is not affiliated with, authorized by, or endorsed by Covestro.
Desmodur N3600 is a registered trademark of Covestro, used here solely for nominative comparison to identify the equivalent grade. RawSource supplies an independent equivalent product; confirm equivalence against your specification and the Certificate of Analysis.
